Comment # 9 on bug 1173727 from Simon Vogl

OK, so I have some very interesting news.
1. The issue somehow does not exist on Arch Linux or KDE neon.
2. The issue does in fact exist on Fedora when using Plasma 5.19.2 from copr,
meaning this glitch is in no way exclusive to openSUSE.
3. The issue seems to be related to plasmashell not shutting down correctly
rather then having problems with startup. The issue can be fixed by doing the
following:
Make a shell script at ~/.config/plasma-workspace/shutdown/ that contains

#!/bin/bash
killall plasmashell

make the file executable.
After this, the issue completely disappears on both openSUSE and Fedora and the
system works as expected. I think this is something the KDE developers should
take a look at and it doesn't make much sense to discuss issues that also
affect Fedora in this bugtracker. When I have time I will create a bug report
in the KDE Bugzilla, but for now we can see this issues as resolved as it isn't
openSUSE-specific and a workaround exists.

Again, thank you very much for your support, I hope KDE will be able to resolve
the issue ;)
